4.4. PREPARING THE WELDING UNIT FOR OPERATION TIG – 4T
4.4.1. OPERATIONAL CYCLE OF THE WELDING PROCESS WITH TIG-4T
FUNCTION
The procedure for preparing the welding unit for operation with an external oscillator is an individual
one and should be described in the oscillator operation manual. The connector for remote switching
on and off the welding unit is located on the rear panel of the welding unit. The connection diagram for
the remote switching on and of the welding unit is the same as for the TIG-2T welding process
(see Section 4.3).
1.
Switch on the oscillator for contactless arc starting.
2.
Set switch
(17)
on the rear panel of the welding unit to position I (switching on).
3.
Switch the button
(4)
to the
TIG
welding position, if the desired welding method has been
skipped, press the button
(4)
again - the methods are switched over and over again;
4.
Select the functions of the

. If the
TIG-4T
function has been omitted while selecting, press and hold the button
(3)
again - the
functions switch all the way
5.
Using the buttons
(1)
set the current basic parameter - welding current or parameter of the
selected function;
6.
If required, perform the additional functions specified for the argon arc welding process
(see
Section 6.1).
7.
The device is ready for use.
Enjoy Your work.
ATTENTION!
Use a gated welding torch with a
Ф
13 mm
bayonet connector.
Select the maximum current of the welding torch according to the
specifications
The procedure for changing the values of the operational parameters of the welding unit is described in
